Solving for variable 'x'.

Begin completing the square.  Divide all terms by
2 the coefficient of the squared term: 

Divide each side by '2'.
81 + 1.5x + x2 = 0

Move the constant term to the right:

Add '-81' to each side of the equation.
81 + 1.5x + -81 + x2 = 0 + -81

Reorder the terms:
81 + -81 + 1.5x + x2 = 0 + -81

Combine like terms: 81 + -81 = 0
0 + 1.5x + x2 = 0 + -81
1.5x + x2 = 0 + -81

Combine like terms: 0 + -81 = -81
1.5x + x2 = -81

The x term is 1.5x.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5x + 0.5625 + x2 = -81 + 0.5625

Reorder the terms:
0.5625 + 1.5x + x2 = -81 + 0.5625

Combine like terms: -81 + 0.5625 = -80.4375
0.5625 + 1.5x + x2 = -80.4375

Factor a perfect square on the left side:
(x + 0.75)(x + 0.75) = -80.4375

Can't calculate square root of the right side.
